Security hasp

ABSTRACT

A security hasp for a door which when the door is closed projects forward along side a fixed keeper in position to be locked thereto by a padlock. For security a shrouded padlock is used having a lock case which shrouds its shackle and form a yoke embracing the hasp and keeper from below, and the hasp carries a hood which projects across the keeper and across the yoke opening of the padlock and thereby cooperates with the shrouds to shield the lock shackle from access by a cutting tool.

For security a shrouded padlock is used having a lock case which shrouds its shackle and form a yoke embracing the hasp and keeper from below, and the hasp carries a hood which projects across the keeper and across the yoke opening of the padlock and thereby cooperates with the shrouds to shield the lock shackle from access by a cutting tool.

FOSHEE bzwg x wma ATTORNEYS SECURITY HASP This invention relates to means for providing improved security in a hasp lock arrangement in which a hasp lies along side a keeper and is locked thereto by a padlock.

The terms hasp and keeper" designate two members used to lock doors and the like, which in locked position lie in face to face relation and are locked against displacement by the shackle of a padlock. Commonly, one element moves parallel to and away from the other when the door is swung open. For convenience we refer to the member which so moves as the hasp, and to the other as the keeper, but the invention may be embodied in equivalent relationship in which the terminology may apply differently. We intend the claims to cover such equivalents.

In locked relationship,,the hasp and keeper project in closely spaced parallel relationship and have aligned holes through which the shackle of the padlock extends. For highest security, the padlock case is formed with shrouds which partially surround the exposed portions of the shackle and form a yoke embracing the hasp and keeper from below. In accordance with our invention, the hasp is provided with a hood or guard which extends across the end and upper edge of the keeper and overlaps the shroud portions of the padlock case. Such hood is made of hardened steel or the like and overlies the gap between the hasp and keeper and the gaps between them and the shroud, and thereby shields and protects the lock shackle from access by a saw or other cutting tool.

The accompanying drawings illustrate the invention and show a preferred embodiment exemplifying the'best mode of applying the invention. In such drawings;

FIG. 1 is a side elevation of a keeper and hasp embodying the invention, locked together by a shrouded padlock;

FIG. 2 is a horizontal section taken on the line 2-2 of FIG. 1;

FIG. 3 is a vertical section taken on the line 3-3 of FIG. 1.

The embodiment shown comprises a keeper secured to the edge of a door jamb 12 by screws 14 which are concealed when the door is closed. The door 16 carries a hasp member 20 which as shown is an angle member having a rear mounting leg 22 lying against therear face of the door and a forward leg 24 extending and mortised into the edge of the door and pro jecting forward in face to face relation with the keeper to form a hasp 26. The keeper 10 and hasp 26 are provided with aligned holes 18 and 28 through which the shackle 30 of a padlock 32 is passed to lock the two against relative movement.

The padlock 32 has a case 34 which includes a body for housing the lock mechanism and which forms shrouds 36 and 38 which extend upward about the side of the shackle 30. The shroud 36 about the swiveled leg of the shackle surrounds three sides of that shackle leg 35, while the shroud 38 about the hook leg 37 of the shackle surrounds only two sides of that leg 37 and leaves an opening for such leg to swing out of the plane of the body when the shackle is in unlocked position. As shown in the sectioned portion of the padlock in FIG. 3, the hook leg 37 is retained in locked position in the body by a bolt 40 engaged in a notch 42 in the hook leg 37. A similar bolt (not shown) engages a notch in the swiveled leg 35 of the shackle in a conventional manner.

The upper outer corners of the keeper 10 and hasp 26 are rounded, and the edge of the hasp 26 carries a hood 46. As seen in FIG. 1, such hood, extends vertically from a point at or below the lower edge of the shackle and keeper, upward and inward over the top edge of the shackle, to form a shield or guard in front of and above the position of the shackle as it passes through the openings 18 and 28 in the keeper and hasp.

As seen in FIGS. 2 and 3, the hood 46 projects across the edge of the keeper l0, and projects outward from the outer face of the keeper l0 and hasp 26 a sufficient distance to overlap the shrouds 36 and 38. The shackle-receiving holes 18 and 28 are sufficiently close to the hood that its lower end lies in closely spaced relation with the front face of the padlock body 34. Desirably, the hood is welded to the hasp over the entire length of the hood, conveniently by a weld bead 47 in the corner between such hood and the outer face 21 of the hasp.

In locked relation the parts will have the positions shown and described. The shrouded lock body 34 will form a yoke embracing the keeper and hasp from below, and the shackle will be positioned within the shrouds in position to be largely protected by them. The hood 46 will cover the crack between the keeper and shackle, and will bridge the yoke formed by the shrouded lock body and hence overlie the gaps between the shrouds and the hasp and keeper. Further, the hood will prevent the lock body from being swung forward to expose the shackle from below. The arrangement will effectively protect the shackle from access by a saw or like cutting tool. Also, in the unlikely event that the shackle were cut at one point, the interengagement of the body with the keeper and hasp and the presence of the hood 46 as a stop, would prevent the body 34 from being turned relative to the shackle portion engaged in the openings 18 and 28 as would be necessary to release such shackle portion from its retaining bolt.

When the padlock is unlocked, the shackle is released to permit the body 34 to move downward to the position shown in dotted lines in FIGS. 1 and 3, which would move the shrouds to a position below the bottom of the keeper and shackle so that such body can be turned on the swiveled leg 35 of the shackle, as shown in dotted lines in FIGS. 1 and 2. When the body is so turned, the shackle can be removed from the holes 18 and 28, to release the hasp for movement relative to the keeper and permit the door to be opened. On swinging doors, the hood 46 on the hasp 26 will swing with the door forward away from the end of the keeper 10. On sliding doors, the hood 46 will slide edgewise with the door, across and away from the keeper 10.
